valves, and more particularly to an im-i proved outlet valve-forthe tanks of washing machines.

In theuse of washing machines it is customary to supply fresh water and suds to the tankeach time a new batch of articles It is desirable that the should be as shortas possible, in order to minimize the interruption of the operation of the machine.

The primary object of my invention is to promote the above-referred to desirable result by providing an outlet valve for the tanks of Washing machines, which may be quickly opened and closed, and. which will permit the rapid discharge of the dirty water and suds. p

A further object of my invention is .to provide an improved slide valve which will be firmly held in tightly closed position against its seat, and which may be easily moved away from its seat to fully open the.

outlet which it controls. I

A still further object of my invention is toprovide an improved discharge valve for the tanks of washing machines which will be simple in construction, durable in use, and efficient in operation. v

My invention will be more fully disclosed hereinafter with reference to the accompanying drawings, in which thesame is illustrated and described in a convenient and practical form, and, in which,

, Figure 1 is a perspective view of the tank of acylinder washing machine, having my improved outlet valve appliedthereto,

Fig. 4 is an enlarged sectional view on the line 4c. 4t of Fig. 5 and, Fig. 5 is a plan view looking upwardl with respect to Fig. 4.

Similar reference characters are used to for Washing- Machines, of which the follow,-

designate similar parts in the several figures of the drawings.

Reference letter A designates the cylindricaltank 'of a washing machine, in which is contained the usual rotary perforated cylinder (not shown) for containing the articles to be washed. The heads of the tank are provided with any suitable sup porting means, such for-instance as pairs offeet. a and a adapted to rest on the floor of the laundry. The construction and operation of the washing machine need not be described in detail in order that my invention maybe fully understood, inasmuch as my invention is not limited in its application to any particular type of washing machine, nor in fact to washing machines, as itmay be used to control'outletpassagewhich is secured to the bottom .of the, Cy-

lindrical wall of the tankby any suitable means,a's, for instance rivets. b designates a valve seat which surrounds anoutlet pase sageway in the plate B. The plate B is preferably made of cast metal, and has, formed integrally therewith at each of its corners a downwardly opening socket C, having screw threads on its inner surface. Supported by each of thetubular sockets- C is a'bolt D, having its upper screw threaded end engaged with the screw threads in. the socket. vA lock'nut dis preferably provided on each bolt D to engage the lower end of the supporting socket,.to more securely maintain the oonnection'of the bolt with the socket.

Tracks E and E are supported at oppositesides of the plateB bymeans of the bolts D. Each' of the tracks is provided with holes at its ends, through which the bolts at the front and rear of the plate 13 pass. I The ends .of the tracks rest upon coiled springs F, one of such springs surrounding each bolt D below the end of the track through which it extends. In order that each spring F may be held concentrically around the bolt which supports it, asleeve G, having a circular seat 9 in its lowerend, surrounds each bolt and rests upon its head, the spring F being located on the outside of'the sleeve with its lowerend resting the seat at the lower end thereof. Each of the tracks E and E is provided with an inwardly projecting horirest upon the inwardly projecting horizon.

zontal flange 0 and 6 respectively, upon which 1s supported a'valve H of a s1ze corresponding to that of the 'seat'b surround.

ing the passageway" in the plate B. Depending from oppositesides ogt the valve H are flanges H and H, which overlie and tail flanges 6 and e of the tracks. The depending flanges on the valve are inclined upwardly toward the rear edgethereof, as shown 111- Fig. 4-, so asto cooperatewlth upwardly projecting wedge surfaces" 0 on the flanges ofthe' tracks alining with the edges of the horizontal flanges e and e of the tracks." Lugs T and T are provldedf is as follows: Injorder to open the valve passagewaythroughthe plate B. I

Depei'iding'irom the center of the valve -H are spaced ears h, between which is pivota'lly connected the inner end of a rod K,. the outer end of such rod, being pivot v ally connectedto thelower end of a crank arm L fixed "to 'a" rock-shaft M, suitably" journaled on the exterior of the tank The IOCk-Slittft',M may be supported by means of a bracket m, secured jdrical wall ofthe tank A, and by extending its 'en'd's through'holes in the opposite supto the cylin porting l'egs fof the tank. Fixed'to anddepending from the rock sh aft M, preferably adjacent one end thereof, is a crank'arm'N,

' the lower endof which is connected by a link Wvwit'h the lowerend' of a crank arm 0, fixed at: rock-shaft o. The rock-shaft o is sui abl'y j ournaled upon the tank A, as by means of abracket t, fixed to the rear supporting leg'or the adjacent head of the tank. R

designates a hand lever fixed'to the rockshaftO. t I I :"In order that the valve maybe guided in its r'eciprocations into and out of registry with the outlet p'assage, it is providedwith pair's of depending studs S and S at-its opposite sides, which engage the inner at'the inner endsfof the tracks, which project into the paths of the rear studs S so as tolimit' the inwardmovement ofthe valve wl" en t has reached its tul'lvclosed position;

. 'The'cp'er'ationof my improvedslide valve to perm t the discharge of the liquid contents frond the tank, the hand lever Riis oscillated toward the left in Fig. 1. Such movement of'the hand lever oscillates the rock-shaft '0, and with it the crank arm' 0, wh ch inflt'urn oscillates the crank arm N through the medium of the connecting link it. 'Th 'gsc llation of the crank arm Nrocks the s'h aft M, and thereby oscillates the de-' pending crank arm 'L in adirection away opening. movement of the valve H permit-s from the tank. The valve H is consequently m v w rd the ight upon the supporting 'tracksdb'y .means of the rod K. The

I The valve, therefore, in 1ts movement to fully open position does not contact with the valve seat except at the beginning of its opening movement. Wear upon the valve-and its seat is therefore avoided.-

In order to close the valve the handjylever R is moved toward the right in Fig; '1,

It' will be'further evident' that my improved valve is resiliently supported in closed" posi tion, thereby maintaining a. tight joint'with" its's'eat. i
